CALIBRATION AND MODELING OF NPK BASED ON SOIL FERTILITY FOR LOWLAND RICE GROWN IN SHAHAPUR TAHASILVijay J. Ghodvinde, D.N. Shinde, Prashant P. Lohani, Santosh W. Kulkarni and Sunita S. Gangete
A field experiment was conducted in Shahapur Tahasil (study area is situated at the height of 174m from sea level, latitude 19" 26.874, longitude 73" 20.964, near Liberty Oil Mill) from various villages. The area is facing the problem of low yield because of low fertility, seasonal cropping etc. Hence there is need to analyze soil to check the proportion of various nutrients. Quality and quantity of crop depends upon soil contents but the contents do not remain same all over the nation, they change according to the fertility of soil and atmosphere. Hence soil samples are collected from various villages of Shahapur Tahasil and analyzed by standard methods. On the basis of soil analysis reports soil contents, fertility of soil, type of crop to be taken etc are decided. And also quantity of manure (like dung) and various chemical fertilizers are decided. Some remedies are also suggested to increase the fertility of soil.
